Melbourne Airport is curfew-free and operates 24 hours a day year-round. The terminals are contained within one building, or within easy walking distance of each other. As a gateway to Australia, it has many advantages over other capital cities that are curfew restricted and have complex or expensive arrangements to transfer from international to domestic flights.

The airport has four terminals. T1, T2 T3 are in the same building, and it is easy to walk between terminals, however each terminal has separate security screening and access between terminals is not available once in the sterile area.

Skybus, ☎ +61 3 9670-7992, runs a frequent 24/7 shuttle to and from the Southern Cross Station Coach Terminal on Spencer Street at the west end of the Central Business District, just north of Lonsdale Street. There are two airport pickup locations. One is outside the Virgin Australia (T3), 50 m from the international terminal (T2). The other is outside the Qantas domestic terminal (T1). There are electronic ticket machines for card purchases at the stops. You can also purchase online or at the ticket booths.

The trip takes between 20-40 minutes (in normal traffic, depending on the time of day) and runs directly using the freeway with no stops. It costs $18/36 adult one-way/return, $6 child one-way (4–14 years of age). There are also several family ticket options available. Frequency ranges from half-hourly 1–4AM, to every 10 minutes 5:30AM–11PM. They also run a connection service between the terminal and central hotels/hostels during the day (M–F 6AM–10:30PM, Sa Su 7:30AM–5:30PM), and this is included in your fare. Bookings are not needed for travel to hotels, but book hotel pick-up at least three hours ahead. Otherwise, you can catch a train from Southern Cross Station, or take a tram down Collins St through the city centre.

SkyBus has additional services to Dockland and St Kilda. Further afield it also runs to Frankston and Peninsula Airport Shuttle Service and to the Western Suburbs. The St Kilda and Docklands services operate daily, with buses every half hour on weekdays and hourly on weekends. Prices for this trip are fixed at $19 one-way and $38 return for adults. The Frankston and Peninsula service operates 364 days a year although is less frequent, with a timetable available on the SkyBus Website. Prices for this service vary depending on the final destination, with adult fares ranging from $21 to $53 one way.

There is free Wi-Fi on board the bus, if you're willing to trade your personal details for a Internet fix.

If money is more important than time and convenience, you can take public bus 901 (every 15-30 munutes) to Broadmeadows Station (travel time 20 min) and switch to a train (every 8-30 minutes) to the city (travel time around 40 min). Both buses and trains run from 5AM to midnight, although Broadmeadows is one of Melbourne's sketchier suburbs and you'll want to be careful after dark. There are now Protective Services Officers patrolling almost all stations nightly after 6PM, including Broadmeadows. The trip traverses Zone 1 and 2, and you will need a Myki smartcard to pay the fare ($4.30 from Jan 1, 2018). The smartcard itself costs $6. The SkyBus ticket office also sells the myki Visitor Pack for $14, which includes $8 of credit. You can also buy a card from the Myki machine in the Terminal 3 baggage claim. The buses depart from outside Terminal 4, underneath the short term car park. Follow signage.

If you are using public transport to travel around Melbourne on the day you arrive, this method represents even better value. There is a daily cap on public transport fares, meaning you will never pay more than two fares per day in each zone, no matter how many trips you make. On weekends, the daily cap is $6 for unlimited travel across both zones.

The buses display the next stop, and there will usually many others getting off at Broadmeadows Station. When travelling to the airport, the bus stop is immediately outside the station, and there is an electronic sign indicating the predicted arrival time of the next bus.

Alternatively, routes 478/479 (every 30-60 minutes, travel time 15 minutes) provide service to Airport West, where you can connect with Route 59 trams (every 8-30 minutes, travel time 50 minutes) to the city. The fare is the same ($3.76 from Jan 1, 2015). The tram stop at Airport West is pretty desolate, and you're unlikely to encounter many others taking this route. You may be the only one at the stop.

Taxi ranks are found across from the terminals, and there is no need to book. A taxi into the Melbourne CBD will cost around $60 and take around 30 minutes. Ignore anyone soliciting fares inside the terminal, and proceed directly to the rank. It is illegal to solicit fares.

Options for Melbourne city centre and inner suburbs include Starbus and VHA airport shuttle which charge between $18 and $25 depending on destination.

Alternatively, if heading to southern Melbourne (St Kilda and points beyond), the Frankston and Peninsula Airport Shuttle (FAPAS) runs roughly-hourly minibus services, advance bookings required either on-line or at +61 3 9783-1199. Full adult fares from $18, but there are group discounts and some hostels even offer free rides if you stay for three or more nights.

For Dandenong and surrounding areas Airport Bus Dandenong has services from $20 to the city centre and St Kilda and $25 to Dandenong. Airport Bus Eastside services the outer eastern suburbs and Gull services Werribee ($22) and Geelong ($32).

Some very well known car rental companies have offices and facilities on-site. All of them have information desks where bookings can be made in the domestic terminals. Considering the high cost of using taxis, it may be cheaper to hire for a few days if you want to really explore Melbourne and its surroundings - but also remember to take into account tolls and parking.

The motorway into Melbourne is a toll road, and cameras will scan your licence plate. All the on-airport rental car companies have some option to pay, or you have up to three days after you travel to buy a Tulla Pass for $5.25. Or, if you are spending longer in Melbourne then you can buy another passes that will halve the price, but charge you a setup fee such that is it isn't worthwhile for a single trip to the airport and back.

Unless you have a access issue requiring assistance, Melbourne Airport can only be navigated walking. Expect it to take around 10 minutes to walk from one end of the main airport terminal to the other (Terminals 1 to 3). Another ten minutes to walk to Terminal 4.

This makes Melbourne the easiest Australian gateway ports for transit, as Sydney, Brisbane and Perth all have awkward transfers between International and Domestic terminals.

Terminal 1: Qantas maintains a Qantas Club and Qantas Domestic Business Lounge in this terminal for eligible flyers. The Business Lounge is in the Qantas Club Lounge. The lounge is to the right after going through security

Terminal 2: Terminal 2 is host to a range of lounges for the various international airlines that operate from the airport. Lounges for eligible flyers include the Emirates First and Business Class Lounge, the Qantas First Class Lounge, Qantas Business Lounge, Air New Zealand Koru Lounge, Cathay Pacific Lounge, Malaysia Airlines Lounge, Singapore Airlines Lounge and United Airlines Lounge.

Terminal 3: Virgin Australia maintains a lounge in this terminal for eligible flyers. The lounge is landside and you must clear security after leaving the lounge.

Terminal 4 is a terminal built for budget airlines with self-service check-in and bag drop facilities. Terminal 4 requires a fairly lengthy walk to the boarding gates from the security check-point and departure lounge. There are no travellators and there is very little seating along the walk and at the boarding gate areas. The terminal centers around the departures lounge area, with screens not showing the departure gate until the flight is ready to board. Passengers should pass through security and wait in the departure lounge area until the screens indicate that it is time to go to the gate. The departure lounge has seating, a food court and various retail outlets.

There are no places of interest in the surrounding area, and limited ways of getting to the few around. If you need to stretch your legs and get some fresh air, walking between Terminal 4 and the main terminals is probably the best way of doing it.
